I offer to proofread and improve tutorials for $8 USD per 500 words, initially.
Relevant Skills and Experience
I´m American, a native English speaker, currently living in Brazil. I used to write, translate, proofread and edit reports, correspondence and technical manuals for multinational companies in the oil business, and now perform the same services for university students who wish to publish their academic work in perfect English. I use the Track Changes function of the Word program to organize my corrections and comments on the text.
Proposed Milestones
$45 USD - Deliver corrected tutorials for $8/500 words.
I would be glad to do your sample exercise to demonstrate my skills and style. I would also like to know more about the subject(s) of the tutorials. I recently edited the slides for a business school course in Supply Chain Management, and am currently editing a self-help book, so I have experience in somewhat similar teaching presentations.
